Cruise from Miami to two beautiful islands on this 5-day itinerary. If you’re looking for treasures, Puerto Plata has many, from its beaches to the world’s most transparent amber. The Victorian-mansion-turned-Amber Museum opened in 1982. History fans will want to see the home of Christopher Columbus. At Great Stirrup Cay, the island is yours to explore and enjoy. Relax on the beach, pet a stingray, snorkel the underwater sculpture garden or jet around on a Wave Runner.
